Mustaine has also revealed that Megadeth are gearing up to start work on the follow-up to 2013 album Super Collider. Speaking at the Classic Rock Roll of Honour, he told Nicky Horne, host of the Classic Rock Magazine Show: “We’re commencing the writing process right now and we’re going to start in January of next year. We’ll be touring in August with a very huge English metal band in the States in South America, and we’re hoping to get our record out sometime in the summer.”

My best guess would be Iron Maiden again which makes sense since Maiden is due out for a new album some time next year.
